5 | | -- requires an amplifier on the PWM output pin, e.g., [this one](http://www.tinyurl.com/magicmouth/) |
6 | | -- original implementation by Clive Webster in [Webbotlib](http://webbot.org.uk/iPoint/30.page) |
7 | | -- ported to Arduino by [Gabriel Petrut](http://www.tehnorama.ro/minieric-modulul-de-control-si-sinteza-vocala/) |
8 | | -- Stephen Crane modified it to use pins other than pin 10 with the help of [this tutorial](https://sites.google.com/site/qeewiki/books/avr-guide/pwm-on-the-atmega328) |
| 5 | +- requires an amplifier on the PWM output pin (see below) |

10 | | -- note that it works with [ArduTouch](https://github.com/maltman23/ArduTouch) by setting output on pin 9. |

| 27 | +- [manitou48](https://github.com/manitou48) added support for Leonardo |
| 28 | +and ARM processors with DAC (Teensy, Due) |

|
16 | | -- add support for ARM processors with DAC |
17 | | -- PWM filter not required with DAC, but still need audio amp and speaker. DACs can source only about 1 ma |
18 | | -- tested on Teensy 3.1, 3.5, 3.6, LC, and DUE |
